Specification of Letters Patent.

Patented April 16, 1907.

Application filed August 29, 1905. Serial No. 276,278.

To @ZZ whom t may concern:

Beit known that I, JOHN H. MOKINNEY, a citizen of the United States,residing at Shreveport, in the parish of Caddo and State of Louisiana,have invented a new and useful Freezer, of which the following is aspecificaf tion.

' to contain ice-cream of the same or of different Vwhich will behereinafter more fully described, and pointed out in the claim.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings, Figure 1 is a view, partly in section and partly inside elevation, of a freezer constructed in accordance with the presentinvention; and Fig. 2 is a section on line 2 2, Fig. 1.

- Referring to the figures by characters of reference, 23 designatessupporting-standards suitably connected and upon which are journaledtrunnions 22 and 22', which are secured in any suitable manner to thepolygonal heads 2() of an outer polygonal casing 16- `One of the facesof this casing is formed by a door 17, which is hinged, as at 18, and isadapted to be fastened in closed position by means of any suitable lock,such as disclosed at 19. Secured upon the inner faces of the heads 20are polygonal heads 11,the edges of these heads 11 being parallel withand at equa distances from the edges of the heads 20. The heads 11 aresurrounded by an inner polygonal casing 10, one face of which is formedby a door 12, which is hinged, as at 13, and adapted to be secured inplace by means of a suitable lock 14. The door 12 is disposed directlyinside the door of the outer casing, so that by opening the outer door17 access may be easily had to the inner door, which inner door iscapable of being swung open into the door-opening in the outer casing.The inner-and outer casings form a continuous annular ice-compartmenttherearound, and which extends uninterruptedly throughout the length ofthe two casings. Access to all portions of this compartment may be hadby simply opening the outer door `17, whereupon ice may be easily packedwithin the annular compartment, so as to completely surround the linnercasing 10. The walls of this annular compartment 'are completely coveredwith suitable heatexcluding material, as shown at 21, and the innercompartment formed within the casing` 10 is, also lined throughout witha suitable heat-excluding material 15. A crank 24 is connected to thetrunnion 22 to facilitate the manual rotation of the entire freezer.

- In using the freezer herein described the same is rotated until thedoors 17 and 12 are uppermost, whereupon the two doors are opened and aquantity of ice mixed with saltis placed within the inner casing 10.Icecream molds or receptacles 25, which may be of any desired sizes andshapes, are then packed within the ice in the casing 10, after -whichsaid casing is entirelylled with ice and the door 12 closed and locked.A miX- ture of ice and salt is then tightly packed within the` annularcompartment formed by the outer casing 16, and after this compartmenthas been filled the outer door 17 is closed and locked. The freezer canthen be rotated, so as to cause agitation of the ice and anyice-waterwhich might be produced therein, and after the molds 25 have been withinthe freezer for a predetermined period said freezer is moved in positionwith its doors uppermost and the upper door 17 is opened and the icecovering the door 12 is removed. Said door 12 is then also opened andthe ice and molds within the inner compartment removed. An additionalsupply of ice and molds can then be placed in the inner compartment, ifdesired. Should the operator wish to remove all of the contents of thefreezer, it is merely necessary to open the two doors 12 and 17 and turnthe freezer until said doors are in their lowest position, whereupon theice, &c., will slide by gravity out of both compartments of the freezer.By providing casings which are shaped as shown and with walls inclinedtoward the dooropenings said inclined walls constitute hoppers fordirecting all of the contents of the compartments toward the openingswhen the freezer is inverted.

What is claimed is- In an ice-cream freezer the combination Withsupports; of an outer polygonal casing, a` door constituting one Wall ofthe casing, those Walls of said casing adjoining the door being inclinedtoward the door to constitute a hopper when the casing is inverted,trunnions extending from the ends of the casing and journaled on thesupports, polygonal heads secured upon the inner faces of the ends ofthe outer casing, an inner casing secured upon and surrounding saidheads to form an inner casing concentric With the outer casing, therebeing an outer annular compartment around the inner casing, said annularcompartment extending uninterruptedly throughout the length of the innercompartment7 a door constituting one Wall of the inner casing anddisposed adjacent the inner face of the door of the outer casing, twoWalls of the inner casing being inclined toward the door-opening in saidcasing to form a hopper When the casing is inverted, and means forrotating the casings simultaneously to invert them.

In testimony that I claim the foregoing as my oWn I have hereto aflixedmy signature in the presence of tWo Witnesses.
